JavaScript Array slice()

JavascriptWeb DevelopmentFront End TechnologyObject Oriented Programming

The slice() method of JavaScript is used to return the selected elements in an array.

The syntax is as follows −

array.slice(start, end)

Above, start parameter is an integer specifying where to begin the selection, whereas, end is where the selection ends.

Let us now implement the slice() method in JavaScript −

Example

 Live Demo

<!DOCTYPE html>
<html>
<body>
   <h2>Demo Heading</h2>
   <p id="test"></p>
   <script>
      var arr = ["Accessories", "Electronics", "Books", "Pet Supplies"];
      document.getElementById("test").innerHTML = "Initial array = "+arr+", <br>Sliced =          "+arr.slice(2, 4);
   </script>
</body></html>

Output

Example

 Live Demo

<!DOCTYPE html>
<html>
<body>
   <h2>Car Variant</h2>
   <button onclick="display()">Result</button>
   <p id="test"></p>
   <script>
      var car = ["Hatchback", "Convertible", "SUV", "AUV", "MUV"];
      document.getElementById("test").innerHTML = "Initial Array = "+car;
      function display() {
         document.getElementById("test").innerHTML = "Array after slicing some elements =    "+car.slice(1,4);
      }
   </script>
</body></html>

Output

Click “Result” button −
